UAV Approach Path Control Using Target Face Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems cannot accurately identify the direction a target faces in captured image data, which is crucial for effective tracking and service provision by unmanned aerial vehicles (UAVs) and mobile robots.
Innovation Solution
An information processing device and method that includes an acquisition unit for capturing image data by UAVs and a direction identification unit to analyze the data, identifying the direction a target faces by recognizing features such as facial or bodily orientations, and controlling the UAV or robot's movement based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerial image capturing is performed by UAV to obtain captured image data, then the ability to track and provide services to targets is improved, but the ability to identify the direction a target faces is insufficient
Solution Approach 1:
The patent segments the target object into multiple feature points (e.g., facial features, body landmarks) and analyzes their relative positions and orientations independently. By dividing the target into key characteristic points, the system can accurately determine the direction the target faces even from aerial views, resolving the contradiction between tracking capability and direction identification accuracy.
Data Source
AI summary
A device and method for acquiring captured image data obtained by an unmanned aerial vehicle (UAV), identifying a direction that a target appearing in the captured image data faces, outputting an approach curve used to move the UAV from a current UAV position to a UAV position closer to the face of the person based on the identified direction that the face of the person faces, where the approach curve includes an arc portion connecting the current position to a straight line portion at an approach contact point located a predetermined distance in front of the face of the person, the straight line portion connecting the approach contact point to the position closer to the face of the person.
